A website name generator that works from your actual vocabulary is useful. One that matches your naming style is essential. Choose a direction — brandable, descriptive, compound, portmanteau, or abstract — and we'll surface domain name ideas tuned to that style.
Short made-up words that feel like a brand. The easiest to trademark and own. Some famous examples include:

Short, tech-adjacent suffixes like -hq, -labs, and -io are often used to signal that a product is developer-friendly and geared towards technology enthusiasts. These suffixes help convey a modern, innovative vibe and suggest a focus on cutting-edge features and tools. See example keywords below:
Our generator expands your keyword in five ways so every search returns hundreds of available names — not a dead-end. Here's exactly what the AI tries behind the scenes:

Each TLD has its own search tool with live availability, pricing data, and market stats. Pick any extension and start searching.
A domain name generator is a tool that creates available domain name ideas based on keywords you provide. Instead of manually checking names one by one, you enter a word or phrase and the generator produces dozens of available options instantly. Instant Domain Search's domain name generator uses AI to suggest creative combinations, checks availability in real time, and shows pricing from multiple registrars so you can register immediately. Learn more in our guide on how to use an AI name generator.
Enter one or more keywords and our AI analyzes them to generate relevant domain name combinations. It looks at synonyms, related concepts, word blending, and common naming patterns to suggest names you wouldn't think of on your own. As suggestions appear, we check availability across 800+ extensions in real time and show you pricing from multiple registrars. The AI learns from millions of successful domain names to prioritize short, memorable, brandable options. Read about the technology behind it in our building fast AI research post.
Yes, completely free with no signup required. You can generate unlimited domain name ideas, check availability, compare registrar pricing, and save your favorites to your saved domains list. We make money through small referral fees when you register a domain through our registrar links. The price you pay is the same as going directly to the registrar. All of our tools are free: the main domain search, the aftermarket search, the bulk checker, and this generator.
Yes. Enter two or more keywords separated by spaces and the generator combines them in different ways: joined together, hyphenated, reversed, blended, and with prefixes or suffixes added. More keywords give the AI more to work with. For example, entering "cloud" and "sync" might produce cloudsync.com, synccloud.io, gosync.co, and dozens of other variations. The more specific your keywords, the more targeted the suggestions. Our guide on how to come up with business name ideas has tips on choosing good seed keywords.
Three things. First, we check availability in real time as suggestions appear. Most generators show you a list of names and then make you check each one manually. Second, we show pricing from multiple registrars side by side so you can find the cheapest option for any name. Third, our AI generates truly creative suggestions, not just "your-keyword-online.com" padding. We also integrate with our aftermarket search so you'll see if a taken domain is actually for sale, and our extensions page so you can explore every TLD option for a name you like.
Keep it short (ideally under 15 characters), easy to spell, and easy to say out loud. Avoid hyphens, numbers, and double letters that cause confusion. If possible, choose a name that hints at what your business does without being so literal that it limits future growth. A made-up word (like Spotify or Zillow) can work if it's memorable and pronounceable. Test it by telling people the name verbally and seeing if they can type it correctly. Read our full guide on how to name your business for a deeper breakdown.
Absolutely. Many people use the generator purely for brainstorming business names, product names, or project names. You can save your favorite suggestions to your saved domains list and come back when you're ready to buy. There's no account required and no limit on how many searches you can run. If you want even more brainstorming tools, try our business name generator which focuses specifically on brand-friendly naming.
If every .com variation is taken, you have options. Check alternative extensions like .co, .io, or .ai on our extensions page. Look at the aftermarket to see if someone is selling the .com you want. Try completely different keywords or naming approaches (our guide on unique business name ideas can help). Or search for expired domains where previous .com registrations are becoming available again. Sometimes the best domain isn't the first one you thought of.
